Idea/suggestion for Glacial and Cursed Blade changes

Personally I think it feels really bad when you lose to glacial's freeze, way worse than any other comp. Other comps also have some form of counterplay to them; build Dragon's Fang vs. sorcerer comps, Phantom Dancer vs. assassins, Rapid Fire canon vs. yordles etc. But there is no way you can build against glacial to have a better chance, and your opponent doesn't even need more than 2 glacial champions to be in a good spot with his proc chance. These are the reasons I think the Glacial proc should be adjusted in some way. I had a few ideas: A. Decrease the freeze time of the proc (shorten the length of time a champion is frozen by the proc) B. Introduce a cooldown to the proc (example: Elise gets frozen by the glacial proc and upon being unfrozen she cannot be frozen again for x seconds) C. Rework Cursed Blade (the proc of which has been controversial since the start) to be Mercurial Scimitar; this item could cleanse cc once per round or it could give you Tenacity (lower cc duration by x%) or something similar). The last idea is personally my favourite, as it also reworks Cursed Blade. It's proc is in my opinion too strong to be in game, it will either proc so little it won't matter and it will be a bad item, or it will proc enough or even too much and be borderline overpowered. I'd just like to add that my intention here was not to make Glacial's bonus useless, it was to bring it in line with others, make it less frustrating to play against. I'm also not a game designer, or a stats specialist. This all comes from my personal experiences and views and if rioters disagree with my opinion of Glacial needing readjustment, I understand fully. These are all just suggestions.
